asset_get_type

Description

With this function you can get the type of asset being referenced from its name (a string). One of the constants listed below will be returned.

Syntax:

asset_get_type(name);

Argument	Description
name	The name of the game asset to get the type of (a string).

Returns:

Constant

Constant	Description
asset_object	The given name refers to an object.
asset_sprite	The given name refers to a sprite.
asset_sound	The given name refers to a sound.
asset_room	The given name refers to a room.
asset_tile	The given name refers to a tile set.
asset_path	The given name refers to a path.
asset_script	The given name refers to a script.
asset_font	The given name refers to a font.
asset_timeline	The given name refers to a time line.
asset_shader	The given name refers to a shader.
asset_unknown	The given name refers to an asset that either does not exist, or is not one of the above listed.

Example:

if asset_get_type("pth_Path_" + string(global.Game)) == asset_unknown
   {
   show_debug_message("Path doesn't exist!!!");
   }
else
   {
   path_index = asset_get_index("pth_Path_" + string(global.Game));
   }

The above code checks a dynamically created asset name to see if the asset is of the correct type. If it is not, then a debug message will be shown, otherwise the asset name is used to assign the asset to the instance.

这个函数是根据asset的名字，来获取它的类别，返回的类型为系统提供的常量，简单易懂。
